Blood vessels, veins, in your body that facilitate the return of blood from your extremities back to the heart. Venous insufficiency is a when the flow of blood through your veins is resisted. It can be caused by many conditions of the veins, particularly by varicose veins.”
Causes of Venous Insufficiency
In normal veins, there is an unimpeded flow of blood from your extremities back to your heart. Valves inside your veins of the legs that stop the backflow of blood. Venous insufficiency is when the forward flow through the veins is blocked, as in a blood clot, or if there is backward leakage of blood flow through damaged valves. In many cases of venous insufficiency, patients have both obstruction of forward flow and backward leakage of the veins. Blood Clots and Varicose Veins are the most common causes of venous insufficiency. Additionally weakness of the leg muscles that help squeeze blood forward may also contribute to venous insufficiency.
